Commercial HVAC Service in Susanville, CA

I had an excellent experience with Advanced Comfort Control. They came out the same day I called, quickly diagnosed the issue, and completed the repair during the same visit. After the repair, they thoroughly tested the system to make sure everything was working properly before leaving. The technician was professional, polite, and transparent throughout the entire process. He clearly explained what was wrong, what needed to be repaired, and answered all of my questions without any pressure. I really appreciated the honesty and quality of service. I’m extremely happy with the entire experience and would definitely recommend them to anyone needing HVAC service.

Advanced Comfort Control recently repaired my air conditioner, they came out the day after I called them. Which was wonderful, diagnosed and came back in a few days and installed a new fan motor. Very professional and I couldn't be happier with the prompt response and repair. They also worked on my furnace last winter and did a great job then too in a timely manner. Thank you very much to the Harkness family and associates of Advanced Comfort Control, Inc.!!

Had a solar system put in by the team. They did great work, also had a heater installed in our shop. Works fantastic. We also have had repairs to our heater hoses lines, under house and repairs on our heat pumps/ air conditioning units. The guys at Advance Comfort always were on time, helpful, and curious. When needed will call again. Thanks Bill.

This company was so helpful. It was freezing and my monitor broke everyone else had a wk wait. These guys were on it within a half hr they were at my place and in another half hr they had my place nice n toasty with heat . They are awesome and good at what they do. Good price house call.. I definitely recommend them.

I have used Advanced Comfort Control for 3 different installations. 2 mini-split systems (one at our home and one at our church, and a home generator system). I rely on them for their honesty, quality and reliability. They are easy to contact in an emergency (I had to get heater working for my dad in middle of winter). They do warranty work when there was an issue with the manufacturer product. Zero problems after 7+ years of service. When you call an hvac company, remember, they will be going through your entire house for the installation, warranty work and maintenance. Get someone you trust.
